Be it known that I, FREDERIG LUTHER ing at Hamden Junction, Vinton and State of Ohio, h

lowing is a specification.

his invention relates to car-wheels of that class which are sometimes known as selh lubricating and which are formed with a re- I ceptacle for lubricating material of a liquid. or viscous nature which as the Wheel rotates upon its spindle is gradually supplied to the caring. I

The objects of the invention are to simplify and improve the construction and operation of this class of devices, and with these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction ant novel arrangement and combination of parts, which will be hereina tter fully described, and particularly pointed out in the claim.

in. the drawings, Figure l is a side elevation of the car-wheel constructed in accord ance with the principles of the invention. Fig. a vertical sectional view of the same. *ig. of the Wheel, showing the same disconnected from the. axle. Fig. 4 is a perspective detail view of the locking-washer detached.

Corresponding parts in the several figuresare indicated thriiiug'hout by similar characters of reference.

The improved car-wheel of this invention is composed of a hub 1, spokes 2, and arim 3, having a flange 4, the same Formed as one integral casting.

The hub l is formed in the usual manner with an aperture 5, constituting, an axle-box, and surrounding said aperture is cavity (5. which conununicates with the axle box through slots 7 in the walls of the latter. The front side of the hub. has an aperturei, into which is threaded a casing f), in the outer end of which is seated a ball-valve 10, nor mally forced to its seat by a spring, 1], contained in the casing and the tension of which is regulated by means of a screw-plug 12. The sides of the casing are provided with openings 13, and the outer end of the casing is provided with a non-circular head 14, con stituting a wrench-seat, whereby said casing may be screwed. into position.

i an annular recess 15, in which SMITH, a citizen of the United States, resid' pvmsher 16,, of felt or similar compressible and in the county of l are invented a i new and useful Car-W heel, of which the fol- 'nate at thejiacc of the hub 1.

3 is a perspective detail view of the hub l being usually a recess or I constituting a lubricant-receptacle I In the'rear side of the hub 1 there is formed is seated a bibulous material. Surrounding the recess 60 15 there is formed an annular flange 17, in which is placed an rdi.nary washer 18, the flange 17 serving also to accommodate the collar 19 of the axle 20, the spindle of which extends through the axle-box. 6 "iheouter end of the hub has a. recess 21, surrounded by an annular flange 25 and forming a seat for a washer 22, of felt or similar compressible o r bibulcus material.

, Within the flange 25 there is also placed a 7d locking-washer 24, provided with arnis 225,

engaging recesses 26 in the flange 23, with which the said washer is thus placed in locking-engagement, so as to rotate with'the wheel.

The radially-extending reccsses'26, located 7 5 in the flange L0, are provided at their outer ends with portions or extensions 26", which pass along the sides of the flanges and termi- The arms 25 of the washer 24 extend in the same plane as .80 the body of the washer and enter the radi ally-extending recesses 26. The said arms 25 are provided with the upturnedfends 25, which enter the portions 26 of the said re cesses. The said arms 25 and. their ends 611- 8 5 tering the recesses in the 'nanner above described prevent the leakage of oil and keep the interior of the hub free 1' cm dust. I

After the wheel is placed. or mounted in position for rotation upon the s indie 27 of 90 the axle 20 it is secured, prefcrabl y, by means of a cotter-pin 28, a washer 29 being interposed between said pin and the locking- Washer in order to take up slack and to prevent direct frictiimal contact between the 95' locking-washcr and the cotter-pin.

When the wheel rotates upon. the s indie, the lubricant will pass through the slbts 12 and will spread in a thin 'film between the surfaces of the spindle and the axle-box, thus kcepingsaid surfaces well andsulliciently lubricated. The lubrlcantthat passes to ward the cndsof the spindle will become absorbed by the felt washers l6 and 22, which latter, as they absorb the lubricant, will expand and press tightly against the spindle, thus preventing the escape and wasteful use of lubricating materialit will be observed that the washers 16 and 222 will be compressed to some extentby the washers 18 no and 24 contiguous ther to; but the washer- 16, which is accommodated within the flange said Washer engage ifihe recesses 26 in the Hence the Washers 16 and flange may not be compressed by the :11 scent rigid Washers to an extent'whieh wound iiiterfei'e with their capacity for sbsm'lting oil a ml for Wiping ille surface of the spimlle in such manner as to keep the lath? well lubricated withoui danger of was 0.
